rangement ofthe timing mechanism for con-k f l.trolling the ignition, andthe objects of the invention Vare to provide, first,I a timing mechanism which may readily vbe replaced as the case may be, and second,-.a timing mechanism for controlling the time at which the spark may occur in the periodofthe cycle of the engine and also forthepurpose of regulating the',` speedat which Vthe centrifugal controlling means kmoves out of engagement with its cooperating contact.`

'6 6 of Figure l; and

WithV these and other objects inv view',- my invention consists in ithe novel Vfeatures. of construction, combination and arrangement of parts as will behereinafter referred -to and more particularlyv pointed out in *they specication and claims. Y ,v

With reference to the accompanying drawmgs, Y

Figure 1 yis a vertical sectional'view on the line 1 1 of Figure 2; v l Y Figure 2 is a vertical sectional-view taken on the line 4 4 vof Figure 1,'

Figure 3 is a detail enlarged sectional view taken on the line 5-5 of Figure 1; l

Figure 4 isl a sectional view on the line Figures 5, 6 and 7 are detail plan views of the timer vtrack and Vits supporting and operating rings.

' Referring more particularly vto the drawings byV numerals of reference, 2 designates generally the engine and 3 the cylinderthereof provided with the air cooling fins 4.' The cylinder, in the present instance of the vertical Atype is mounted upon the crank case 5 to which it is secured'by stay bolts 6, the crank case in turn being supported upon the base 8 being fastened to it by bolts 10.

. The piston 11 is connected by pitman rod 12 with the crank 14 of the two-part counterbalancing head 15 ofthe divided crank shaft. the latter comprising shafts 16 and` 18, one of which 16, carries a splined drive pulley y19. kThe opposite Zshaft'18 has splined vthereto a belt `pulley 20, which through a fbelt 2l drives a fanr22 journaled ina bracket 211' on the cylinder. Y'

One of the principali features of this Ainvention resides in the particular' construci tlonand arrangement of theV governor mecha-V nism` and spark control, and to thisl end, thereis .pivotally mountedon the inner wall of thebelt pulley 20 a centrifuga-llyactuated contact arml 50'` normally :urged into contact with a normally fixed timer track lhaving "a.contact 52 ,through a coil spring 54,;the

tension on which'may be regulated by suitable means. The timer track comprises a ring of insulating material, the, inner wall ofwhich is provided lwith a series of spaced recessesVV 56y for 'the5reception kof a series of tongues"59 formed 'on f and bent at right angles l.to the plane of a supporting ring 60,vr

said -ringhavingwa radialarm 61 termin ating *in a lip 62 havingan aperture63. ',To the I Y .fV

contact member ,52:is electrically connected,

'one end of a conductor '64', the other en d65 of which ypassies through an elongated opening66 in. the radial' arm 61.l v

Thesupporting ring isin turn carried by av flat ring 68 through the medium of opposed tongues 69 which engage over vdiametrically opposed flattened portions -70 of the track supporting ring V60, and tonguesy 72 Yarranged on opposite sides of a radial arm 74, formed with theflatring 68. The outer endof the arm 74 is bent at' right angles Vto lits plane as at 841 and provided with a threaded aperture 75 for the reception of a-screw 7 8',`the inner end of'which latter is swiveled in the opening 63'7of the radial arm 61'. The screw 78y is turned by a handle 7 9 to shift'the track supporting ring 60 radially of the flat ring 68 forthe kpurlpose of adjusting the position of the contact 52 with relation to the "brush 82, and thereby regulating thespeed of the motor. .The

entire assembly, comprising the timer track 51,v and rings 60 and 68 Vissupported on the vsideof the crank casethrough the medium of anfannular'series of `spring clips 80 se cured by suitable fastening screws 81. The

clips 8Ov engage over the outer periphery `of V the ring 68 and permit it, with vthe ring'60 vand track 51 to be oscillated so that the relation of the contact in the ycycle ofmovement of the piston with respect to the contact arm' 50 having contact brush 8,2 may be adjusted toladvance or retard the timingof 2L 1 Y V1,591,032

grounded. While thev ignition circuit is completed through the conductor 64 which. also is arranged to pass tlirougli, the elongated opening 66 in the arm 74 of t'l'ie flat' ringT 68'; The opera-tion of the engine should' bethoroughly Yfamiliar-to those skilled in Ytlie artA in View of the foregoingspeeilicatien.
